Definitions

  • the invention relates to a method and an apparatus for processing animal pelts.
  • the skinning of the animal bodies preferably results in tubular shaped pelts arranged with the skin side of the pelt turned outwards and the fur side of the pelt turned inwards. After the skinning, leftovers of e.g. meat, fat, sinews and the like is removed from the skin side of the pelt.
  • a step of the processing of the pelts often comprises tumbling the pelts with the skin side facing outwards together with a liquid absorbing granular material such as sawdust to remove the remaining leftovers from the skin side of the pelts and/or to dry the skin side.
  • a known apparatus for tumbling such animal pelts comprises a drum with a compartment comprising a tumbling section and a separation section.
  • the tumbling section is adapted to tumble the pelts together with sawdust, and at the separation section the drum wall consist of a metal grid for separating the sawdust from the pelts before unloading the pelts from the drum.
  • the drum is arranged with an angle in relation to horizontal so that the pelts during rotation of the drum are transported from the tumbling section to a separation section due to gravity.
  • WO 2008/101505 relates to a tumbler for dead animal bodies and pelts.
  • the tumbler comprises a number of sections, and the tumblers are transported between the sections by means of a conveyer unit extending through the tumbler in the longitudinal direction of the tumbler.
  • DE 33 36 050 A1 discloses a drum for processing pelts.
  • the drum comprises one compartment for processing the pelts, and the compartment is formed by an inner cylindrical cage in the form of a grating. Guides are arranged to extend into the compartment from the cage, and upon changing the rotation direction of the drum, the additive is transported to one end of the drum while the pelts are transported towards the other end of the drum to a door to be unloaded.
  • the invention relates to a method of processing animal pelts according to claim 1.
  • This method facilitates an advantageous processing of animal pelts.
  • the skin side of the pelts may be very wet and sticky. This may result in liquid absorbing granular material sticking to areas of the skin during the absorption of the liquid on the skin side of the pelts. Such granular material sticking to the skin side of the pelts may prevent further dry granular material from absorbing liquid at the areas with the granular material sticking onto the skin and may even form a bunch/lump of sticky granular material with an outer substantially dry surface at such areas of the skin side.
  • a result of this is that the skin side of such pelts is not processed enough, and thus, when the granular material has been separated from the pelts after in the separation compartment during the first processing, some of the pelts may need a further processing to achieve a dry and clean skin side.
  • the automatic second processing facilitates that the pelts are processed a second time and thus, a more homogeneous result of the processing of the pelts may be achieved.
  • the method further comprises:
  • the first treatment compartment preferably comprises an inlet for loading the pelts into the drum
  • the second separation compartment comprises an outlet for unloading the pelts from the drum.
  • the method may further comprise said pelts being loaded into said drum to a treatment compartment arranged at a first end of said drum before said first processing, and wherein said pelts are unloaded from said drum from a separation compartment arranged at a second end of said drum after said second processing.
  • the method may comprise that absorbing granular material separated from a separation compartment during said first processing is automatically loaded into a treatment compartment to be reused during said second processing.
  • dry granular material may be blended with more wet granular material which has absorbed liquid during the first processing.
  • the granular material may be suitable for being reused in the second processing thus e.g. reducing the needed amount of granular material.
  • a less complex supply of granular material for the second processing may be achieved.
  • the method may comprise that the said granular material is automatically unloaded from said separation compartment and into a temporary storage compartment in said drum by means of perforations in an inner wall.
  • This may facilitate an advantageous separation of the granular material from the pelts in the separation compartment(s), and an advantageous handling, transportation and/or treatment of the granular material during the treatment process of the pelts.
  • At least one of the said compartments comprises one or more fixed transportation guides extending from an inner surface of a wall of at least one of said compartments, said fixed transportation guides inducing a movement of the content of the said at least one compartment in the longitudinal direction of the drum during rotation of the drum.
  • the transportation guides are arranged with an angle in relation to the longitudinal direction of the drum so that the transportation direction is determined by the rotation direction of the drum. It is understood that the transportation guides may be adjustably arranged in aspects of the invention to facilitate that the transportation guides may be adjusted into fixed positions with various angles in relation to the longitudinal direction dependent of the selected angle.
  • the method may comprise the pelts being prevented from leaving a compartment of said drum for an amount of time during operation of the apparatus by means of a partition wall separating said treatment compartment and said separation compartment and extending from an inner surface of the drum, wherein the ratio between the height of said inner separation wall and the height of said one or more fixed transportation units is no more than 1:4 such as no more than 1:3 and preferably no more than 1:1.2.
  • the method may comprise the step of changing the rotation direction of the drum to change the transportation direction of the content of one or more compartments of the drum.
  • the drum may comprise only one separation compartment and one treatment compartment, and pelts may thus be transported between such compartments by means of amending the rotation direction of the drum.
  • the transportation may be facilitated by one or more transportation guides arranged with an angle in relation to the longitudinal direction of the drum and being attached to a wall of the drum to extend into a compartment of the drum.
  • the invention furthermore relates to an apparatus according to claim 7
  • the wall being arranged for separating an absorbing granular material from said pelts during the tumbling is an inner wall arranged inside the drum with a distance to the outer drum wall.
  • the wall arranged for separating an absorbing granular material from said pelts during the tumbling may be the outer drum wall and the granular material is in such an embodiment unloaded directly to the exterior of the drum.
  • the wall arranged for separating the absorbing granular material from the pelts during the tumbling in the separation compartment preferably comprises a plurality of perforations to facilitate that the granular can leave through the perforations while the pelts are maintained in the separation compartment.
  • the perforations may be obtained by drilling, by die-cutting, and/or the like.
  • the wall may be made from a metal grid made from e.g. braided and/or welded/soldered wires, preferably metal wires forming openings between the wires to obtain the said perforations.
  • the wall comprising the perforations may be made from any suitable structure and material facilitating separating the absorbing granular material from the pelts during the tumbling in the separation compartment.
  • the said drum may comprise a first treatment compartment and a second treatment compartment, a first separation compartment and a second separation compartment, wherein said first separation compartment is arranged between said first treatment compartment and said second treatment compartment in said drum, and wherein said second separation compartment is arranged adjacent to said second treatment compartment.
